Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

▪ Abstract We review progress in calculating the one-loop scattering amplitudes required for
next-to-leading-order corrections to QCD processes. The underlying technical developments …

We propose a version of the QCD-motivated “k⊥” jet-clustering algorithm for hadron-hadron
collisions which is invariant under boosts along the beam directions. This leads to improved …

One-and two-jet inclusive quantities in hadron collisions have already been calculated to
next-to-leading order accuracy, using both the subtraction and the slicing method. Since the …

An up-to-date global QCD analysis of high energy lepton-hadron and hadron-hadron
interactions is performed to better determine the gluon and quark parton distributions in the …

We describe a general method of calculating the fully differential cross section for the
production of jets at next-to-leading order in a hadron collider. This method is based on a …

We compute the effects of soft-gluon resummation for the production of high mass systems in
hadronic collisions. We carefully analyse the growth of the perturbative expansion …

A strong signal for double parton (DP) scattering is observed in a 16 pb− 1 sample of pp→
γ/π 0+ 3 jets+ X data from the CDF experiment at the Fermilab Tevatron. In DP events, two …

I illustrate a general formalism based upon the subtraction method for the calculation of next-
to-leading order QCD cross sections for any number of jets in any type of hard collisions. I …

The impact of recent precision measurements of DIS structure functions and inclusive jet
production at the Fermilab Tevatron on the global QCD analysis of parton distribution …
